LearnPython3theHardWay__Excercise 31 Making Decisions

建议ex27-31连起来学习

迄今为止，我们学会输出字符串和函数，这些基础足够让我们的代码从头开始运行，到尾部结束。现在我们有了if,else和elif，像上一节练习，我们可以开始让脚本做决策了。

注意，使用了 if 的嵌套，另外，脚本内容有点儿童不宜。。。

print("""You enter a dark room with two doors.
Do you go though door #1 or door #2?""")

door = input('>')

if door == "1":
    print("There's a giant bear here eating a cheese cake.")
    print("What do you do?")
    print("1. Take the cake.")
    print("2. Scream at the bear.")

    bear = input(">")

    if bear == "1":
        print("The bear eats your face off. Good job!")
    elif bear == '2':
        print("The bear eats your legs off. Good job!")
    else:
        print(f"Well, doing {bear} is probably better.")
        print("Bear runs away.")

elif door == "2":
    print("You stare into the endless abyss at Cthulhu's retina.")
    print("1. Blueberries.")
    print("2. Yellow jacket clothespins.")
    print("3. Understanding revolvers yelling melodies.")

    insanity = input('>')

    if insanity == '1' or insanity == '2':
        print("Your body survives powered by a mind of jello.")
        print("Good job!")
    else:
        print("The insanity rots your eyes into a pool of muck.")
        print("Good job!")

else:
    print("You stumble around and fall on a knife and die. Good job!")

Study Drills

1. 改编一下脚本的内容，给出更多选择。
2. 写一个完整的新游戏。
